Our square-head bolts with DIN 479 core shoulder in strength class 8.8 have been specially developed for precise and friction-locked clamping operations. The core attachment ensures a centred position in the T-slot and prevents the screw from twisting – ideal for applications with high safety requirements in clamping systems and fixtures. <\/p>\n
